Dear @impersonal,,

You visited Rajgir many times as a child. There you would always visit your family members, staying with them in the guest house on the second floor. Enjoyed the food, environment and Buddha statues and temples there.

In places where religious activities are practiced, everything that exists is mysterious. As people used to think about the high reservoir of Rajgir, bathing there would cure long-term illness.

I actually don't know much about Rajgir but I have heard about Nalanda several times on social sites.
Hope you get a chance to visit that delightful place again soon.
